Description

At CrystalClear, we believe a beautiful pond should be a place you can enjoy. Founded in America with a passion for better pond care, we’ve spent years developing trusted solutions that make maintaining your water simpler and more effective. Our proprietary biological treatments and EPA-registered algaecides help take the work out of pond care, so you can spend less time on maintenance and more time enjoying your pond. For over 20 years, CrystalClear has been a trusted leader in water garden care, helping pond owners get more enjoyment from their water. From powerful algae control and natural water treatments to fish care and diffused aeration, our proven solutions make caring for your pond simple, effective, and rewarding. The Proven Solution in Water Garden Treatments Natural. Clear Water. Guaranteed. If you experience murky water, debris accumulation, or are struggling to maintain a healthy fish population, your pond may be suffering from a lack of oxygen and proper circulation. Increased oxygen promotes a healthier and more balanced aquatic environment and supports all aquatic organisms, such as fish and plants. In addition, increasing oxygen improves water quality by reducing the buildup of harmful gases and organic matter, which can lead to stagnation and foul odors. Oxygenation also enhances the nutrient cycle, aiding in the decomposition of organic material and the growth of beneficial bacteria. CrystalClear KoiAir Aeration Kits are the ideal choice for aerating medium and large water gardens and koi ponds. A powerful yet energy-efficient dual diaphragm SilentAir Aeration Pump infuses your pond with fresh air while the virtual maintenance-free membrane diffuser plate allows for maximum oxygen uptake. Choose between three aeration kit options based on your pond size and start aerating the water in your pond today. High Efficiency Aeration Pump: Running on as little as 17 watts, these whisper-quiet SilentAir aeration pumps are the heart and soul of our KoiAir aeration units. Diffuser Plate Assembly: Each KoiAir diffuser plate utilizes a sturdy base plate and incorporates a 3/8” barbed inlet for quick hook-up. PTFE Non-Stick 6" Membrane Diffuser Stick: Virtually maintenance-free, membrane diffuser sticks resist clogging. Membrane sticks have the same effect as air stones without the maintenance. Self-Weighted Airline: Heavy-duty flexible airline designed to sink the pond’s bottom even when filled with air. EasySet airline is extremely resistant to cuts, snags and kinks. Aeration promotes oxygen which is the lifeline of every ecosystem. Although waterfalls and fountain sprays add oxygen to the water, they are not always enough and should be supplemented with diffused aeration. With bottom-diffused aeration, water is more efficiently circulated, which increases dissolved oxygen levels. Bottom-diffused aeration: In addition, fish love aeration! Your fish will gather around and enjoy the bubbles coming from the diffusers. How do I choose the right size aeration kit? When it comes to aeration kits, finding the right fit is key. Properly sized aeration units will infuse oxygen into the pond, circulate water, and help create a balanced ecosystem. Your fish will be happier and healthier, and you will have reduced excess organic material in your pond – meaning fewer nutrients to fuel algae growth. When selecting an aeration kit, you need to account for pond shape, depth, and shape. How often do you need to replace the diffuser stick? You only need to replace the diffuser if there is damage. If you are experiencing poor performance and low amounts of air coming out of the stick, start by cleaning off any debris or algae that may have accumulated. If cleaning does not improve performance, then most likely the unit needs a compressor maintenance kit. Can my fish get hurt by the diffuser plates or sticks? Our specially designed diffuser plates have curved/rounded edges with no sharp corners. Also, our PTFE diffuser sticks are cylindrical and smooth, with nothing sticking out that could injure your fish. How often should I install a new maintenance kit? We recommend installing a new maintenance kit every year. Over time the compressor diaphragm(s) can become worn, and this wear will greatly reduce the air output of the unit. Installation is easy and there are step-by-step videos of the process. Will a pond aerator keep an open hole in the ice during winter? Aeration kits infuse oxygen into the water by releasing small bubbles from a diffuser stick, which moves the water and allows for gas exchange. In most climates, aeration is sufficient to maintain open water in even freezing conditions. If you live in a colder climate, however, your water garden may need a little extra help during the winter. In this case, a combination de-icer and aeration kit is a great solution. Using them together will ensure that a hole is kept open in the ice, water circulates properly, and dissolved oxygen levels remain high. Additionally, using a pond aeration kit during winter will allow you to use a smaller wattage de-icer, which could help you save money on your energy bill. Are there other steps needed for winter pond care? During the winter, we recommend moving the diffuser sticks to half your maximum depth. This will help reduce ice formation and keep a pocket of warm water for your fish at the bottom of the pond. Can this unit be placed directly pondside? Yes, it is recommended to place the KoiAir unit pondside out of direct sunlight while also ensuring the compressor has proper ventilation. Energy-efficient aeration improves your water quality, so you can get back to enjoying your pond!

600 gal pond
Size: KoiAir Mini, Ponds 1,000-4,000 Gallons
It's been 1.5 years and everything is great. I have the very smallest unit for only a 600 gal pond. The summers here in Augusta are brutal and the unit is under a fake rock. My pond is in the full sun all day long and these summers in Georgia are brutal. So I wonder about some of the other reviews. Maybe I don't have problems since my pond is so small? I haven't had any trouble and it runs 24/7. I run my waterfall with the UV filter during the day, in addition to the aeration. I notice some koi like to sit near the bottom next to the diffuser. I've even considered adding another in the deeper part of the pond, just to keep the water moving more to keep predators confused. Or at least that's what I tell myself. :) ... show more

GOOD QUALITY AT A GOOD PRICE
Size: KoiAir 1, Ponds 2,000-8,000 Gallons
Late this summer our 2,200 gallon goldfish water garden developed a large "muck" build up that no amount of beneficial bacteria would resolve & it was too large a job to vacuum out. I realized that the answer was more circulation/air in the water. After lots of online research I chose the Airmax KoiAir . I installed it a few days ago and here are my initial thoughts: Pump> appears to be very good quality; is heavy and has 4 rubber feet on the base and a carry handle @ the back; easy replacement/maintenance namely a filter and the diaphrams [they do wear out after a while] Weighted airline> love it! as soon as it hits the water its sitting on the bottom and out of sight Diffusers/plate> plate is weighted so it sinks immediately; diffusers have a rubber sleeve that appears to be replaceable Spring Clamps> I don't trust so I used two screw clamps [found in plumbing supply stores] to make sure the airline stayed attached. Surprise Included> discovered that the connector for the diffuser plate is a "check valve" ;was very pleasantly surprised at this [if your unfamiliar with check valves, they are a back-flow prevention devices i.e. they only allow flow in one direction, this protects the air-pump]. Price> after researching several brands of aeration kits for water-gardens I found the KoiAir not the cheapest or highest but the "best bang for your buck" Installation> was a snap and took all of about 10 mins [took me longer to decide where to put the pump!] The air-pump is bigger than it appears in images! Measuring about 8 1/2" front to back x 6" wide x 6 1/2" height; Airmax recommends that you place pump on something to keep water out [i.e. heavy rains], I used a 1 1/2" thick stone block. It is also recommended that you cover the pump for protection from sun/rain, etc. I ended up buying a Airmax True Rock cover. It hasn't arrived yet so will do a review on it when it comes. NOTE: this kit is designed for use in "decorative" backyard Koi/goldfish/water-gardens. It is NOT for a farm [fishing] pond or lake which holds a much larger volume of water than backyard/decorative ponds and thus require a much larger aeration system than the KoiAir1 or 2. UPDATE 3/2017 With Spring here [well almost] I removed the leaf net from my pond and I am amazed! The pond hasn't been that clear for years! If you have problems with muck / leaf build up in your decorative ponds I highly recommend the Airmax KoiAir it does the job!! ... show more

Very powerful Aerator for a 1500 gallon Koi Pond
Size: KoiAir Mini, Ponds 1,000-4,000 Gallons
The media could not be loaded. I just finished constructing a new pond four weeks ago and am still getting it cycled. The volume of the pond is approximately 1500 gallons and 3 feet deep. I was going through a pea soup algae bloom and added a UV clarifier which has really cleared up the water in the last few days. I have now added an aerator. I purchased the CrystalClear KoiAir Mini Water Garden Aerator Kit and received the item on time and within the promised delivery date. The kit consists of the air pump, sinkable air hose and a single diffuser. Installation was very simple and I was up and running within 10 minutes of unboxing. As you can see from the video clip, the kit provides quite a bit of aeration and really agitates the waters surface. I have it located on one end of the pond as the opposite end has the waterfall return. My hope is that the aeration occurs on both sides of the pond with the area in between being the currents formed so we can see the fishes clearly. The pump itself is very quiet and is drowned out by the sound of the water rippling. So it is not that bad at all. The only negative is that the diffuser is not that heavy. It does sink but because of the "strain" on the air hose the diffuser I found that the diffuser wanted to flip over. I used nylon zip ties to secure the diffuser to a small stone and this have kept it upright at the bottom of the pond. So far, after one day of operation, I am pleased. No complaints on the supplier and the operation of the aerator. It is a good purchase and I am very pleased thus far. ... show more

First impressions are great - with 2 year update
Size: KoiAir 1, Ponds 2,000-8,000 Gallons
Update October 2020: Following 24/7 duty cycle the past two years, I noticed that the quality and quantity of bubbles was dramatically waning, even after changing out the foam filter as recommended by the vendor. I opened the unit and discovered several gaskets were worn. I spoke with the vendor and they suggested a rebuild kit that they sell for around $10. Shipping cost doubled that amount, but this is still a reasonable price in my opinion. The vendor supplies all parts that should be replaced. The job is not hard, but I do suggest you try the air flow before installing the main cover, as I hadn’t seated one assembly properly, initially. When I put the pump back onto the diffuser hose, I was surprised that there still was no bubble flow, even though I knew the pump was pushing some air now. I reeled out the diffuser and discovered it had become water logged. I emptied the water and took advantage of the removal to thoroughly clean the diffuser too. All assembled - I’m back in business, just like new again. End of Oct 2020 update. Introduced the bubbler today to my 8000 gallon koi pond. I placed the bubbler at rough center of the oval shaped pond, probably around 3.5 feet depth. The bubbles are of good quality without being a roiling volcano. I think the water action will do a handy job of its primary reason for purchase, which is to keep an open area during freezing New England winters. The fish seem to really like the bubbles too, which is nice. First impressions are quite positive. The device feels and looks to be made with quality materials, including the hose. While I can’t comment on long term of course, I’m very happy with this purchase. ... show more
